Verbena plant named &#39;oxena&#39;

ABSTRACT

A new Verbena plant particularly distinguished by its red-rose flower, early flowering, a spreading habit that is first semi-erect and later spreading.

BACKGROUND OF THE NEW PLANT

[0001] The present invention comprises a new distinct cultivar of Verbena, botanically known as Verbena*hybrida. The new cultivar is propagated from cuttings resulting from the cross of Z752 and Z744. Z752 is a scarlet flowering Verbena having a spreading habit. Z752 is not commercially available and is not known by any synonyms. Z744 is a rose flowering Verbena having a semi-erect habit. Z744 is not commercially available and is not known by any synonyms. Neither Z752 or Z744 has been patented. As a result of this cross the present cultivar was created in 1997 in Enkhuizen, Netherlands and has been repeatedly asexually reproduced by cuttings in Enkhuizen, Netherlands and Sarrians, France over a three year period. It has been found to retain its distinctive characteristics through successive propagations, and this novelty appears to be firmly fixed. This new Verbena plant is an annual in most climatical zones in the US, only in zones 9 and 10 it is a perennial plant.

DESCRIPTION OF THE DRAWING

[0002] This new Verbena plant is illustrated by the accompanying photographic drawing which shows blooms, buds and foliage of the plant in full colour, the colour shown being as true as can be reasonably obtained by conventional photographic procedures.

DESCRIPTION OF THE NEW CULTIVAR

[0003] The following detailed descriptions set forth the distinctive characteristics of this new Verbena. The data which defines these characteristics were collected from asexual reproductions carried out in Enkhuizen, Netherlands. The plant history was taken on 14 weeks old plants, blossomed under natural light in a greenhouse. Colour readings were taken in the greenhouse under ambient light. Colour references are primarily to the RHS Colour Chart of The Royal Horticultural Society of London.

We claim:
 1. A new and distinct variety of Verbena plant, substantially as herein illustrated and described, characterized particularly as to novelty by larger red-rose flowers, which appear earlier on the plant, and a growing habit that is first semi-erect but later spreading.
